Email Open Score Intelligence

The Behavioral Layer Your Data Strategy Has Been Missing

Deliverable is not the same as engaged. And “valid” doesn’t always mean valuable.

For too long, marketers and data teams have been working off static assumptions. Relying on the binary judgment of whether an email can be delivered, rather than whether it’s worth sending in the first place.

AtData’s Open Score Intelligence File changes that. It doesn’t just confirm that an email address exists. It shows whether someone’s on the other end, paying attention.

These signals let you segment, prioritize, or suppress records based on actual activity, not assumptions. Whether you’re building re-engagement campaigns, scoring leads, or training models, Open Score helps you focus on the contacts who are active now, not just technically valid.

Engagement Is the New Identity Signal

The marketing world has changed. Open rates, while imperfect, remain one of the clearest indicators of active attention. And attention, especially recent attention, is everything. It influences inbox placement, signals intent, and often separates the leads that convert from the ones that ghost.

By analyzing real engagement behavior across billions of permissioned signals from our expansive partner ecosystem, Open Score gives you a reliable read on whether a given email address is alive in the ways that matter most. Whether they’re not engaging, or just not engaging with you.

This isn’t a guess. It’s a signal. And it’s always up to date.

What’s Included

Every record in the Open Score Intelligence File is enhanced with real-world engagement insights designed to slot directly into your data workflows:

• Open Score (0-10): A numerical score reflecting the recency and frequency of opens across our network.
• Last Open Date: The timestamp of the most recent engagement behavior detected helps inform the model
• Ability to Tier Activity: Classify buckets such as active, semi-active, or dormant for easy segmentation
• Model-Ready Formatting: Structured to integrate seamlessly with scoring models, suppression rules, and targeting pipelines.

Unlike generic engagement datasets, every signal in the file is drawn from permissioned, real-time behavioral data — refreshed regularly to reflect what’s happening now, not six months ago.

Why It Matters (More Than You Think)

Open Score isn’t a reporting tool. It’s an activation layer—a behavioral filter that sharpens strategy and strips waste. Whether you’re tuning models, suppressing stale records, or segmenting for personalization, Open Score gives you the power to stop assuming and start acting with confidence.

• Re-Engage More Intelligently

  Identify which dormant contacts are still warm enough to be worth reaching, and which are just dragging down deliverability.

• Score Leads (and Risk) More Accurately

  Enhance your churn, fraud, or intent models with real engagement signals that surface who’s still listening.

• Tailor Messaging with Precision

  Align campaign frequency, content, and tone with actual behavior, not theoretical personas.

• Clean and Optimize CRM Data

  Go beyond “is this email valid?” to “is this person even paying attention?” and act accordingly.

• Time Campaigns More Effectively

  Know who’s engaged lately so you can strike while attention is warm, and skip the cold.

Built for the Data-Driven, Not Just the List Builders

Most deliverability tools stop at “yes” or “no.” Open Score takes you further—into the subtle, fast-shifting terrain of real engagement. Because someone opening an email once last year is not the same as someone who opens three times a week.

This is about prioritization. Optimization. Respect for the recipient and your budget. And ultimately, about shifting how you treat email data—from static reference to dynamic reality.

Backed by AtData’s Permissioned Network

Our signals aren’t scraped, inferred, or recycled. They’re earned. Gathered from real engagement behavior across a cooperative network that processes over 100 billion monthly events.

That scale matters. It gives Open Score an unmatched pulse on what’s happening in real-time, across industries and audiences, helping you:

• Prioritize active audiences

  Focus your marketing, modeling, and outreach efforts on users who are engaging today. Not just those who exist in your database.

• Suppress stale or unresponsive records

  Avoid wasting budget and damaging deliverability by removing inactive contacts from campaigns, even if their emails are technically valid.

• Improve segmentation and personalization

  Build dynamic segments based on actual open behavior, so you can fine-tune frequency, content, and timing based on engagement tiers.

• Enhance model performance

  Feed lead scoring, LTV, churn, and fraud models with engagement-weighted signals that reflect real user behavior.

• Protect performance across channels

  Whether you’re driving revenue, engagement, or inbox placement, Open Score helps you focus on what’s working—and pull back where it’s not.

Backed by our trusted network, Open Score gives you a live read on attention, so your strategy stays focused, effective, and grounded in reality.

Email addresses alone don’t tell you who’s listening. Open Score does.
